Abstract

A system comprises a first unit and a second unit communicatively coupled to the first unit. The first unit is operable to receive a first original radio frequency signal and the second unit is operable to receive a second original radio frequency signal. The first and second original radio frequency signals are originally transmitted on a radio frequency channel using time division duplexing. The first unit communicates a control signal to the second unit, the first unit generating the control signal based at least in part on detecting when the first original radio frequency signal is being received at the first unit. The second unit uses the control signal to determine when to output a first reproduced radio frequency signal in accordance with the time division duplexing used to originally transmit the first and second original radio frequency signals on the radio frequency channel. The first reproduced radio frequency signal is derived from the first original radio frequency signal.
